Title: Power driven saws
IPC: B23D49/04
Filed: 1972-02-14
Abstract: 1384903 Reciprocating saws F A COLSTONILES and A M THOMSON 13 Feb 1973 [14 Feb 1972] 6824/72 Heading B5L A saw assembly comprises a base 10, a support frame 15 pivotally mounted on the base and adapted to support a power hand drill 32 in a predetermined position on the support frame, means, e.g. a clamp 31, for securing the drill 32 to the frame 15 in said position, and a carrier 17 slidably mounted on the frame 15 and having means for releasably securing a saw blade 19 thereto. The carrier 17 is coupled to transmission means on the frame with an input member 26 of which the chuck of the drill 32 is engageable when the drill is in said position, the transmission means being operative to convert continuous rotary movement of the input member into reciprocatory movement of the carrier. The input member 26 is integral with or carries a worm 25 which drives a worm-wheel 24 connected with the carrier 17 by a link 21. Arms 18 of the carrier have split ends to receive the saw blade 19 which is held by screw clamps 20 or spring loaded devices. The base 10 carries a vice 11 for clamping a workpiece, a lug 13 to which the frame 15 is pivoted at 14 and a stop 34 to limit movement of the frame 15 towards the base under gravity and possibly spring pressure. A strip 12 is provided to support the workpiece to ensure that it is cut completely through. Alternatively the base 10 is recessed to receive the saw blade. In a second embodiment the base has a pair of parallel arms in each of which is threaded a screwed bolt carrying a V-section clamp for engagement with one side of a tubular workpiece.

Title: Improvements in or relating to gas cookers
IPC: F24C3/08
Filed: 1942-05-22
Abstract: 556,136. Gas cooker hot plates. HERMANN, R. May 22, 1942, No. 7034. [Class 126] A hot plate or ring of a gas cooker preferably made from or incorporating a material of high heat conductivity is formed with a flat top but of diminishing thickness from the centre to the outer edge to obtain a substantially uniform distribution of heat over the top surface. Fig. 3 shows a copper hot plate 10 having an inverted conical under surface formed with depending fins 11, and coated with a corrosion resistant layer 12 of iron, steel, chromium, aluminium, or other metal or alloy. The hot plate 10 is supported above the burner 14 by a metal shell 13 having a metal lining 17 or a fireclay or steatite lining coated with a bright or polished metal layer to reflect the heat radiated by the burner on to the hot plate. Instead of the fins 11 the underside of the hotplate may be grooved recessed or formed with depending pegs. The hotplate may alternatively consist of a flat cast iron plate having a copper plate formed with fins secured to its lower surface or the whole hotplate may be of cast iron having inserts of copper or other highly conductive material secured within it as described in Specification 555,301. In another construction a mould coated with a thin layer of heat and corrosion resisting metal is filled with a mixture of powdered iron and copper the proportions of iron to copper gradually varying so that one surface is pure iron and the other pure copper. The contents of the mould are then sintered together. In a further construction a hollow iron plate of compressed iron powder has bores or recesses filled with copper powder and the whole is compressed or sintered together.

Title: Improvements in preferential wave transmission travelling wave tube apparatus
IPC: H01P1/15
Filed: 1959-03-02
Abstract: 919,348. Discharge tube non-linear and logical circuits. GENERAL ELECTRIC CO. March 2, 1959 [March 31, 1958], No. 7224/59. Class 40 (6). [Also in Group XL (a)] A wave expander circuit and an AND-gate for a binary digital computer employ a travelling-wave tube 41 (see Group XL (a)) providing two outputs whose relationship depends on the amplitude of the input signal. The circuit to the right of the terminal 40 acts as an expander. With a small amplitude input signal to the travelling-wave tube the two output signals differ in phase and amplitude by amounts which are compensated, by a delay element 43 and an attenuator 44 so that cophasal signals of equal amplitude are applied to the input arms 46 and 47 of a hybrid junction 48. The entire output power is dissipated in a member 50 and no power is delivered by the output arm 51. With a large amplitude input signal to the travelling-wave tube bunching saturation of the electron stream occurs and the difference in amplitude of the output signals increases with the result that unbalanced signals are applied to the arms 46 and 47 of the hybrid junction 48 and an output signal is obtained from the arm 51. The hybrid junction 48 may be modified to operate with antiphasal input signals. The complete circuit shown provides an AND-gate. First and second input signals each representing information in binary digital code are applied to the input arms 55 and 56 of a hybrid junction 57. The arrangement is such that the input signal to the travelling-wave tube is of sufficient amplitude to produce an output signal from the hybrid junction 48 only when coincidence occurs in the two input signals. The hybrid junction 57 may be replaced by a simple T-junction.

In order to indicate which particular area of an aerial photograph under examination by photogrammetric apparatus is being inspected, in relation to the area of the whole photograph, this area is indicated on a separate completely visible screen or photograph. In the form of apparatus shown, two movements at rightangles, which can be the movements of the carriages displacing the aerial photograph in the x and y directions, or else the similar movements of the optical observation apparatus, are applied to two potentiometers 9, 10. As the potentiometer settings vary, they control the movement of moving coils 13, 14 respectively. These coils have mirrors 15, 16 attached, the mirror axes being at right-angles to each other. A light beam is projected from a source 17 so as to reflect from mirror 16 to mirror 15, and then on to a copy 21 of the aerial photograph, attached to a glass sheet 22. The spot of light on the photograph 21 executes co-ordinate movements corresponding to the movements applied to potentiometers 9, 10, and shows which area of the photograph is being examined.
